2、Rodigas WP 3948-a Page 1 of 13 FINISHED PARTS, PLASTICS, EXTERIOR WSK-M98P6-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE This specification defines performance requirements for finished exterior plastic parts consisting of various components and/or materials. The numerical values not defined within this
3、 document will be specified on this document table found on Engineering Drawing. 2. APPLICATION These parts are generally used for various exterior applications (e.g. radiator grilles, body side moldings, name plates) when specific part performance specifications are not established. 3. REQUIREMENTS
4、 General Definitions regarding Requirements and Test Methods. Based on the construction of the finished parts the requirements are divided into various material groups (see Table 1 for recommendation of requirements for different material groups). Test requirements vary in respect of application and
5、 are defined by the methods as specified (see Table 1). Specified test requirements (test conditions) are as specified on Engineering drawing for the finished part. Test according to para 3.4, 3.5, 3.6, 3.7, 3.8, 3.9 and 3.10 of Table 1 shall be carried out on the complete finished part or a represe
6、ntative section of the finished part containing all material groups. Each material group shall be evaluated separately. Surface requirements (from para 3.11 onwards) shall be tested separately for each material group (see Table 1). They shall be tested only if not already tested to individual materi

Material specification requirements
8、are to be used for initial qualification of materials. A Control Plan for ongoing production verification is required. This plan must be reviewed and approved by the relevant Ford Materials activity and/or Ford Supplier Technical Assistance (STA) prior to production parts submission. Appropriate sta
9、tistical tools must be used to analyze process/product data and assure consistent processing of the materials. Part producers using this material in their products, must use Ford approved materials and must conform to a process control plan which has been approved by STA and/or the relevant Material
10、s Activity. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS Ford Motor Company, at its option, may conduct infrared and/or thermal analysis of material/parts supplied to this specification. The IR spectra and thermograms established for initial approval shall constitute the reference standard
11、 and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material conditio
